Any fix for Blueprint Editor lag?

This makes working in blueprints pretty much unusable. I’m not sure what’s causing it as I’m using the latest drivers for my GPU, the latest version of Windows 10, I’ve reinstalled both the engine and launch numerous times and even attempted a few restarts just for good measure. Still no difference there is massive within all the UI in editor and in blueprints it becomes basically unusable. The search features don’t work and the PIE window will freeze for upwards of 5 seconds when launching. This is not a hardware limitation, with an i7, 980ti and everything being drawn from a pair of SSD’s I can rule that out. I also closed any other running programs including Precision XOC and any other hardware monitoring stuff. I’m hoping jumping to 4.14 will fix it however if possible I’d like to find out what’s causing it and stay on 4.13 to avoid duping my projects again.

You can see it towards the end of the stream here but it persists throughout
